great review! i have a tokyo mauri with a detachable red dot, i got rid of the stock red dot and put on a laser pointer flashlight and it works wonderfully!! mine is around 400 fps and cost me $119 on Airsoftmegastore.com i replaced the standard mags with a ultra hi cap mag that uses high cap m4 mags, and holds over 1600 rounds! ive never had a problem even in the cold winters of montana lol
